Management device and management system

Abstract

When an abnormality that disables charging and discharging is detected, the processor estimates a predicted recovery time until recovery from the abnormality, in accordance with a type of the abnormality. The processor sets the charging and discharging vehicle equipped with the battery that was connected to the EVSE when the abnormality was detected as a vehicle to be used for the electric power supply-and-demand plan after the EVSE's predicted recovery time has elapsed.

What is claimed is: 
     
         1 . A management device that manages an electric power supply-and-demand plan for a plurality of electric power regulation resources, each of which is electrically connectable to an electric power system via charging and discharging equipment, the management device comprising:
 a processor; and   memory that stores a program executable by the processor, wherein the processor   estimates, when an abnormality that disables charging and discharging is detected, a predicted recovery time until recovery from the abnormality, in accordance with a type of the abnormality, and   sets an object vehicle, in which is installed an electric power regulation resource that was connected to the charging and discharging equipment when the abnormality was detected, as a vehicle to be used for an electric power supply-and-demand plan after the predicted recovery time elapses at the charging and discharging equipment.   
     
     
         2 . The management device according to  claim 1 , wherein the abnormality occurred in the object vehicle. 
     
     
         3 . The management device according to  claim 2 , wherein the processor
 selects, when the abnormality is detected, a vehicle to be connected to the charging and discharging equipment instead of the object vehicle, from among a candidate vehicle group used in the electric power supply-and-demand plan at the charging and discharging equipment, and   adds the object vehicle to the candidate vehicle group.   
     
     
         4 . The management device according to  claim 3 , wherein:
 an order of connection to the charging and discharging equipment is set for each vehicle in the candidate vehicle group; and   when adding the object vehicle to the candidate vehicle group, the processor determines the order of connecting the object vehicle to the charging and discharging equipment based on the predicted recovery time.   
     
     
         5 . A management system, comprising:
 charging and discharging equipment;   a plurality of electric power regulation resources, each of which is electrically connectable to an electric power system via the charging and discharging equipment; and   a management device that manages an electric power supply-and-demand plan for the electric power regulation resources, wherein the management device   estimates, when an abnormality that disables charging and discharging is detected, a predicted recovery time until recovery from the abnormality, in accordance with a type of the abnormality, and   sets an object vehicle, in which is installed an electric power regulation resource that was connected to the charging and discharging equipment when the abnormality was detected, as a vehicle to be used for an electric power supply-and-demand plan after the predicted recovery time elapses at the charging and discharging equipment.
